Frequently Asked Questions
What is an IBAN?
An IBAN (International Bank Account Number) is a standardized international numbering system used to identify bank accounts across national borders. It consists of a country code, check digits, and a Basic Bank Account Number (BBAN) whose format varies by country.
How does IBAN validation work?
IBAN validation uses the MOD-97 algorithm defined in ISO 13616. The country code and check digits are moved to the end, letters are converted to numbers (A=10, B=11, etc.), and the resulting number must be divisible by 97 with a remainder of 1.
Is this tool suitable for banking transactions?
This tool validates the format and check digits of an IBAN but does not verify that the account actually exists at a real bank. Always confirm account details with your bank before making transfers.
